The South African type ZE tender was a steam locomotive tender.
Type ZE tenders were rebuilt from Type ZC tenders which had entered service between 1896 and 1902. The rebuilding resulted in a tender with a larger water tank and larger coal bunker.[1][2]
Contents
Origin
The original 7th Class locomotive and tender were designed in 1892 at the Salt River works in Cape Town, under the supervision of H.M. Beatty, at the time the Cape Government Railways (CGR) Western System's Locomotive Superintendent.[1][2][3]
Type ZC tenders entered service as tenders to 7th Class locomotives between 1896 and 1913, built by Dübs and Company, Kitson and Company, Neilson and Company, Neilson, Reid and Company, North British Locomotive Company and Sharp, Stewart and Company.[1][2][3][4]
Rebuilding
Between 1912 and 1941, probably c. 1930, several of the Type ZC tenders which had entered service with the Class 7A in 1896, the Class 7B in 1900 and the Class 7C in 1902, were completely rebuilt by the South African Railways (SAR), by mounting a completely new upper structure on the existing underframe, with larger water tanks and a larger coal capacity. The water capacity was increased from Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). and the tender sides were built up to increase the coal capacity from 5 long tons 10 hundredweight (5.6 tonnes) to 8 long tons (8.1 tonnes). These rebuilt tenders had a more modern appearance, with smooth sides all the way to the top. They were designated Type ZE.[1][2]
Letter codes
Since many tender types are interchangeable between different locomotive classes and types, a tender classification system was adopted by the SAR.[2]
The first letter of the tender type indicates the classes of engines to which it can be coupled. The "Z_" tenders could be used with the following locomotive classes:[2]
- CGR 7th Class of 1892, SAR Class 7
- CGR 7th Class of 1896, SAR Class 7A
- Imperial Military Railways 7th Class, SAR Class 7B
- CGR 7th Class of 1902, SAR Class 7C
- Rhodesia Railways 7th Class, SAR Class 7D
- New Cape Central Railway 7th Class of 1899, SAR Class 7E
- New Cape Central Railway 7th Class of 1913, SAR Class 7F
The second letter indicates the tender's water capacity. The "_E" tenders had a capacity of between Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value)..[2]
A number, when added after the letter code, indicates differences between similar tender types, such as wheelbase or coal bunker capacity.[2]
